Classification of placers located at the confluence of streams of low, medium and medium-high order

Abstract

Paleogeomorphology of bedrock near streams confluence and ore distribution were studied with special reference to three metal placers regions. Regular features are discerned in the structure of junctions of streams of different order; placer formation mechanism is clarified taking into account channel characteristics in the confluence zone. The data obtained are used as a basis for classification of stream confluences and related placers. The classification may be used when planning geological works.
